Prickly Pear painting

Day 1 

We have been needing a painting or something over the sofa.  Since we have cactus and hummingbirds, I came up with the idea that I would give that combo a try.  I have never painted prickly pear, so I was ready to give it a try.  This is day one...laying in the outline and some of the color.  One thing that makes it more challenging --I only have yellow, blue, 3 greens, white, and red to work with.   This picture may no be true to life, but so what...
